Given numbers are 642,202,405,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,202,405,629 is 5506058430.
Find LCM of 642,202,405,629 with Prime Factorization
2 | 642, 202, 405, 629 |
3 | 321, 101, 405, 629 |
107, 101, 135, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 101 x 135 x 629 = 5506058430
Therefore, the lowest common multiple of 642,202,405,629 is 5506058430.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
642 x 202 x 405 x 629 = 33036350580
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
642 : 1, 2, 3, 6, 107, 214, 321, 642
202 : 1, 2, 101, 202
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,202,405,629, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
202:2x 101
405:3x 3x 3x 3x 5
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 33036350580/(1x6)
LCM = 33036350580/6
LCM = 5506058430
Thus, we can understand that the LCM of 642,202,405,629 is 5506058430.
